Bluetooth: Under Gnome I can not enable and disable bluetooth from linux. Have to run the windows program which controls bluetooth and enable it. After reboot it will remain enabled (the led indicates it). However there is a hardware switch which turns off all radio communications (including Bluetooth, Wireless Lan, and WAN (3G)), and there is also the possibility to disable each one of them separately from BIOS.

Kubuntu 7.10 (Gutsy Gibbon)

Used Kernel: 2.6.22-14-generic

There are some subtle differences to the Ubuntu installation mentioned above, so I make a separate section. I also made a non-standard installation by using LVM over dm-crypt to get an entirely encrypted disk, except the /boot partition.

The following features work out of the box:

LAN

WLAN

Power Management

Sound (without hotkey support!)

Bluetooth

The following features did not work:

hibernate

Entering and waking up from hibernation took a bit too long, giving me a bunch of too-fast-to-read USB errors on the console screen before shutting down. Notebook also stays blank screen mode after wakeup, until pressing the "enter" key to provoke a wrong password entry in the screensaver dialogue.

suspend to RAM

Waking up from suspend to RAM does not work, the backlight of the screen is not reactivated. Need to reboot to reactivate.

hotkeys

The hotkeys for adjusting the brightness, mute, volume up/down and ThinkVantage do not work. Using "acpi_listen" shows, that some of the keys are recognized, so Kubuntu does not interpret them correctly. Some keys are not recognized at all. Here is an overview:

Key pressed

result

FnPos1 (brightness up)

ibm/hotkey HKEY 00000080 00001010, video LCD0 00000086 00000000

FnEnde (brightness down)

ibm/hotkey HKEY 00000080 00001011, video LCD0 00000087 00000000

Mute

first time: METHOD UCMS 00000000 00000000, after that: nothing

Volume down

first time: METHOD UCMS 00000000 00000000, after that: nothing

Volume up

first time: METHOD UCMS 00000000 00000000, after that: nothing

However, adjusting brightness with KDE Powermanager does work, as well as adjusting volume using Kmix. You can also "echo" values into /proc/acpi/ibm/...

WWAN (UMTS)

I have not tested it yet, I am still looking for a good UMTS flatrate. The device does show properly identified during bootup (use dmseg if you did not pay attention :) and should be usable via kppp.

ThinkLight works, but the other Fn buttons does not: brightness, battery, sleep, etc.

Suspend and Hibernation does not work. Hibernation seems to work, but after saving the session and poweroff, the system wake up automaticallly.

Clock restauraton works.

I still work with driver vesa. It works fine, and makes what I want when I hire an extenal monitor (poweroff the laptop monitor and use the external one), but I have some problems when I logout from X and go to text terminal (ALTF1) without external monitor. The screen turns blank.

I don't know if TurboMemory is recognized. I would like to configure it as swap partition.
